mman AND DISTRIBUTOR.

Application led March '20, 1922l Serial No. 545,329. Renewed January 26, 1926.

This invention relates to improvements for igniting the vcharge in internal combustion engines and it is more particularly adapted for use in those engines in -which tleenethod of high tensionigni'tion is api P The primary object of the invention is to provide a compact device whereby one induction coil may be used with ay source of current and the increased voltage distribated and 'timed to cause the ignition of the compressed gases in any number of the coacting cylinders with less wiring, fewer parts and more economy of space than or'- dinaril Y em loyed.

An er o ject of the invention is to provide a distributor wherein thercentral stem or trunk conductor is connected bysuitable devices at proper intervals to terminals disposed on the inner face of" a cylindrical. casing orshell, which terminals are in turn connectedto cables at the end of the casing for distributing the current to suitable translat'- ing devicesor spark plugs provide an etlcientmeans for varying the time occurrence of the sparksrelatively to thev cycle of operations so thatA the spark may be advancedor retarded as the varymoy require. Y .y

Another object of. the invention is to yprovide a timer having a revoluble contact member and a plurality of contacts inthe shell of the timer, and meansto periodically close the same primaryv circuitl between each contacty and a vibratory coil, and anotl'rerserir-s of contacte in theshell ofthe time, the said coil beingalso in circuit with a device carried by the contact maker rotatingrl in the shell to successively kdistribute the high tension current; to the last named contacts andV thence to corresponding spark lu f i Agsstill further objectA of the invention is to 'rovidea mechanism which may be easily an quickly dismounted and remounted for purposes of examination, replacement orrepair, andkto include in a smally oompassa timer and distributor for the ignition current comprising a distribmtorpartA forcenveying the secondary ignition or sparkcurf A after set forth. Mytimer and distributor rent of the coil to theA leadsiofj thevvan'ous plage of internet combustion 'eng-fins,

- A further object of ther invention is to `rand of the cover ;4 and ing` speed of the engineer other conditions u which will be described below,y in view, the inventionk consists in the construction, arrangement, combination and operation lof parts hereinafter set forth, the Whole forin ing a comparatively simple organization which is reliable and eilicient in practical use.

Referring particularly to the drawings, the, reference numeral 1 denotes `a motor equipped with my ignition device, and indicates inthe present instance a four cylinder internal combustion enginey carrying spark plugs 2, 3,l 4f and 5 respective-ly Iconnected with terminals 23 in"my timer and distributor by cables 2', 3', 4 and 5.` n A revoluble primary Contact Amember 16 is enclosed Within my timer. and distributor y,andis rotatcd'by, a rotary shaft 6 which may be suitably connectedvvith theengine shaft, as for example-by gears 7 My vibratory coil is designated at 8 andmay be connected with` a wire 9y of a source of ypovver as the battery 9, or Witha wire 26 of a magneto. In cases Where abattery is used itv may be grounded by a wire 10. The coil is also `put in electrical vconnection with my timer by the Wire 11 of the primary circuit of the coil yand the/Wire 12 of. the secondary circuit, vin which circuits the primary and secondary contacts are located as hereinpm'prises, en insuietaggsheil er' body perf of caitighlwliviiig, a cyiel hold in, fpioditcm 'ai byurws' le and a lea'f spring 20. A rotatable insulating disk 15 is carried around by the membei1 16 being positioned above an annular ledge or rim 18 of the casing, the shaft 6, sleeve contact member 16 and rotatable disk 15 all being concentric. The said disk 15 serves to divide the casing 13 into two compartments, in the lower one of which are located the primary circuit interrupting devices and in the upper portion thereof are contained the secondary circuit switching distributing means.

By the revolution of the said sleeve 16, which is preferably keyed to the shaft 6, the primary circuit is alternately interrupted and completed by the Contact member or actuator 16 which is spring oontrolled and located at the end oi the member 16 and makes electric connection seriatim with the contacts formed by the open end leaf bowed springs 17 which are arranged to provide a series of spaced contact points all ot which are connected by the conducting ring 211 and are located in the primary circuit of the coil 8 by the wire 11 ruiming from one of the stationary primary contacts on bindingr posts 11 ot' said springs to the said coil.

On the under side et the cover 14: a conducting ring' 19 is located which ring is interposed in the secondary circuit of the coil S by means of the wire 1Q running from the secondarir terminal or binding post 12 near its periphery of the cover to the said coil. A conducting string finger 21 carried by a section 15 ot the rotatable disk 15 bears continuously against the ring 19 and ai preferably spring controlled movable secondary distributor or arcuate member 22 attached to said finger consecutively contacts during' every revolution thereotI the adjustable secondary distributing contacts 23 which are respectively placed in circuit with the spark plugs 2, 3.., 4 and 5 by the connecting cables 2, 3', l and 5',

The shell 13 may have a suitable support, as at Q5, and be held to the same by the spring 2O and adjusted for timing purposes by the manipulation ot' the lug Q5 carried by the said shell. The high tension contacts in the casing 13 may be adjusted so as to lie flush with the interior face ot the shell as at Q3 in Figure 10 andy cimtact therewith may be made by a roller 22 supported by resilient means BO carried bv the section 15 ot the rotatable disk 15, thus providing a spring support for the roller on each side ofthe same.

It will thus be noted that I have devised means wherein in apparatus of the class described one ot cach oa plurality of contacts consecutively closes or interrupts the same primary circuit o'f a single vibratory coil by a suitable Contact member, which eol is also in circuit with a device carried by the revoluble contact member, the said device being constructed and arranged to distribute at the proper time the high tension current from th'J said coil to various spaced contacts arranged in the path ol' the contact member and therefore to each corresponding cylinder of the internal combustion engine.

l wish it to be understood that I do not desire to be limited to the particular use or the exact details of construction shown and described, for obvious modifications will occur to persons skilled in the art.

That I claim as my invention is 1. In a device of the class described, a casingV carrying distributor terminals and a fixed terminal attached to a conducting ring having resilient fingers. a cover therefor having a high tension terminal and a conducting ring connected therewith, an intermediate rotatable block with a resilient conducting brush in electrical Contact with the high tension conducting ring and adapted to successively engage the distributor terminals, and a spring` contact adapted tor simultaneous rotation with said block and located in the path of said resilient fingers.
